Exercise helps the brain rejuvenate and repel the risk of dangerous dementia

The most recent studies have shown that exercise can protect the brain from disease, including Alzheimer's disease, dementia in old age.

Even since ancient times, not only doctors, but also human beings have known about physical activity to keep their bodies healthy. But recent studies also show that physical activity, playing sports, not simply keeping the body healthy but also having the ability to heal and work to prevent many chronic diseases such as Severe cardiovascular disorders, osteoporosis, depression or even cancer.

Sports is a preventive and therapeutic therapy for many pathologies.

It is INSERM (France's National Institute of Health and Pharmaceutical Research) that has made a clear conclusion: sports is a preventive and therapeutic therapy for many pathologies , even, the effectiveness of exercise Sport sometimes even exceeds drugs.

In 2016, French lawmakers passed a law that allows doctors to prescribe 'sports activity' to patients with chronic diseases instead of drugs. So the concept of "prescription sports" was born.

But the latest research is even more surprising when it comes to exercise that can protect the brain from disease, especially Alzheimer's disease, dementia in old age or in other words, make the brain rejuvenate. compared with age. Many large studies have shown that proper physical activity throughout life reduces the risk of later memory problems.

Exercise can protect the brain from disease, especially Alzheimer's disease.

Specifically, a recent research program has tracked more than 1,000 Swedish women for more than 4 decades. The results showed that for those who are considered to be physically fit for cardiovascular exercise, the initial manifestations of dementia have been delayed by up to 10 years compared to those who can medium level force.

Although research has not yet eliminated other confounders, it may affect the risk of dementia such as genes or ways of life, and there are still many other scientific questions that need to be examined. break.

In another research program, scientists have also infected a serious genetic form of Alzheimer's disease on female mice. Later, these mice were treated by combining methods to promote the development of new brain cells and therapies to protect these cells from injury, simulating beneficial effects. of exercise in preventing memory decline. Another is a gene that enhances the level of BDNF protein (Brain Derived Neurotrophic Factor), a brain metabolism cell.

It is the newly born young neurons that will hold the responsibility of protecting the memory later.

According to Dr. Rudolph Tanzi, a neuroscience specialist at Harvard University School of Medicine, Boston, and also a co-author of the study, found that the newly born young neurons will hold the responsibility to protect the ministry. Remember later. But in people who have suffered from Alzheimer's, the brain has become a 'hostile environment' , so BDNF proteins will act as 'street knights' to clean up the environment so that new neurons are born. can "live well".

The next step is to have mice with Alzheimer's into a diverse environment, including a merry-go-round to help reduce the plaque in the brain, which is due to protein fragments β-amyloid, pathogen.

Through a series of memory tests such as entering the labyrinth to learn and remember which areas contain sunflower seeds, sick mice were given physical activity by the ferris wheel with the number of nerve cells. where the hippocampus doubles and has a better memory than sedentary mice.

Not all fitness exercises are suitable for all patients.

In hippocampus, the major brain structure for learning and memory, there are neural progenitors that are responsible for developing new brain cells. And it's where the mice train their fitness, and there are signs of these neural progenitors.

Because research shows that not all fitness exercises are suitable for all patients. So scientists are still studying what new fitness exercises are the most suitable exercise for everyone's brain.
